I carry 2 knives almost constantly. One is the ever present Leatherman Tool, old style and the other is Swiss Army Adventurer. I like the tweezers for splinters and use the tooth pick. This is not your standard Swiss Army knife. This is the 4" lock back single blade, awl and phillips screwdriver on the back side, and flat blade bottle opener, and the last blade is the can opener. Between the 2 of them, I'm fairly prepared for light maintanance or mechanical problems that can be easily fixed. I use them daily. One of my pet peeves, is a dull knife and I keep mine razor sharp.
